Concomitant use of congo red staining and confocal laser scanning microscopy to detect amyloidosis in oral biopsy: A clinicopathological study of 16 patients
No full textTwenty oral biopsies from 16 patients were analyzed both by traditional microscopy and by confocal
laser scanning microscopy. Using conventional histopathological techniques, the diagnosis of amyloidosis
was confirmed only in 15 biopsies. Using confocal laser scanning microscopy, amyloid deposits
were detected in all of the samples. The current study shows that confocal laser scanning analysis helps
to identify minimal amyloid deposits that could be overlooked using traditional microscopy, thus raising
the sensitivity of oral biopsy up to 100%
Temporomandibular disorders in psoriasis patients with and without psoriatic arthritis: an observational study.
No full textTemporomandibular disorders in psoriasis patients with and without psoriatic arthritis:an observational study. Aim. Psoriasis is a chronic, remitting and relapsing inflammatory disorder, involving the skin, nails, scalp and mucous membranes, that impairs patients’ quality of life to varying degrees. Psoriatic arthritis (PsA) is a chronic seronegative, inflammatory arthritis, usually preceded by psoriasis. Temporomandibular disorders (TMD) is a generic term referred to clinical conditions involving the jaw muscles and temporomandibular joint (TMJ). The aim of this study was to assess symptoms and signs of TMD in psoriasis patients with and without PsA. Methods. The study group included 112 patients (56 men, 56 women; median age 49.7±12 years) with psoriasis; 25 of them were affected by PsA. A group of 112 subjects without psoriasis (56 men, 56 women; median age 47.7±17 years) served as controls. Signs and symptoms of TMD were evaluated according to the standardized Research Diagnostic Criteria for Temporomandibular
Disorders (RDC/TMD). Psoriasis patients were subgrouped according to the presence/absence of PsA and also by gender, to assess the prevalence of traditional TMD symptoms and signs.
Results. Patients with psoriasis, and to an even greater extent those with PsA, were more frequently affected by TMD symptoms and signs, including an internal TMJ opening derangement (OD) than healthy subjects. A statistically significant increase in TMDs, OD, bruxism (BRUX) and temporomandibular joint sounds (TMJS) was found in patients with PsA as compared with psoriasis patients without arthritis and controls. Conclusion. Psoriasis seems to play a role in TMJ disorders, causing an increase in orofacial pain and an altered chewing function
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
